Product Description

Chemical Building Material PVA Polyvinyl Alcohol Powder Bulk Price

Solubility PVA is soluble in water, the higher the water temperature, the greater the solubility, but almost insoluble in organic solvents.The solubility of PVA varies with degree of alcoholysis and degree of polymerization.Partial alcoholysis and low degree of polymerization of PVA dissolved very quickly, while full alcoholysis and high degree of polymerization of PVA dissolved slowly.General rule, the effect on the solubility of PVA, alcoholysis degree is greater than the degree of polymerization.The dissolution process of PVA is carried out in stages: affinity wetting, swelling, infinite swelling and dissolution.

Film-forming PVA is easy to form film, its film has good mechanical properties, and the tensile strength of the film increases with the increase of degree of polymerization and alcoholysis.

Adhesive PVA has good adhesion with hydrophilic cellulose.In general, the higher the degree of polymerization and alcoholysis, the stronger the bonding strength.

Polyvinyl alcohol powder is an excellent water-based adhesive. Generally, the product is flake, granular or turbulent, and it must be heated when cold water is not easy to dissolve. After being finely pulverized and surface treated, it can make it have better cold water solubility. However, due to its thermoplasticity, it has high requirements for crushing processing. Yida adopts a unique liquid nitrogen low-temperature cooling process to ensure the uniformity of the powder material, so that it has excellent water solubility and adhesion.

Production Process    

Polyvinyl alcohol is polyvinyl alcohol with different degrees of alcoholysis that is saponified under the action of different amounts of alkali to produce polyvinyl acetate through polymerization reaction of vinyl acetate. The cold-soluble polyvinyl alcohol powder is made from part of the alcoholysis polyvinyl alcohol through cryogenic milling. It is a water-soluble environmentally friendly white solid powder
